Approximately 800,000 people in the UK have dementia. The vast majority of those are diagnosed after the age of 65 – but around 17,000 people have been diagnosed with dementia in their early 60s, 50s, 40s and, in some cases, 30s. On Tuesday 4 February at 10am Victoria Derbyshire will broadcast from the country’s only dedicated day support service for young people with dementia. It’s called the Young Onset Dementia Centre and throughout the programme we’ll hear from some of the people who use its services and their family and friends.
